Majestic Transformer Co.Industrial Cased ThreePhaseTransformers
Our transformers in this range are suitably protected by a sheet metal case. They are normally wall mountable up to 2250VA and floor standing above this rating. Many requirements are for isolation and/or conversion of threephase machines, or creation of a neutral where none is available. Our standard cases are IP33 but we can supply up to IP66 if required, usually with little or no addition to the supply lead-time. All our isolation transformers incorporate an electrostatic screen between...

Infolytica CorporationMagNet Application: 3-phaseTransformer
The model presented here is the simulated results of the ohmic losses and flux density of a 3 phasetransformer with a three limbed paramagnetic core ( m_p 8.0412 x?10?^(-3) N A^2 ). The symmetry in the z-axis has been used to minimize the problem size and accelerate solution time. The coils are made of three concentric layers of different thickness.

Yaskawa America, Inc. - Drives DivisionCreating New Opportunities with Single-phase Power
Waukegan, IL. The Drives & Motion Division of Yaskawa America, Inc. is pleased to introduce the Single Phase Converter (SPC) which converts single-phase power to DC power for use by Yaskawa 's variable frequency drives. The SPC is the solution for the most significant problems facing business owners that power medium-sized motors in rural areas. They can be faced with high costs to run three-phase power, limited single-phase motor options, and a wide range of quality issues. The Single Phase...

Schaffner EMC Inc.An Important Read: EMI FiltersThree-phase power can be drawn by either the Delta configuration or the Wye configuration. In the Delta configuration, two of the power wires are combined to create a circuit that looks like an equilateral triangle (or Delta). A neutral is combined with any of the power wires in the "Wye " configuration. Three-phase electric power is a common method of alternating-current generation, transmission and distribution. Indeed, most AC power is produced and distributed as three-phase power with three...

The Current Transformer (CT) is used to sense AC current in single-phase or three-phase mains circuits. The CT typically has a 1A or 5A AC secondary that connects to a current, power or energy meter. This allows the meter to be located away from the mains wiring. CTs are available in a variety...

A neutral is a connection to an electrical system. In a three-phase WYE configuration, one end of each of the three generator or transformer windings is connected to a common point. This common point is called the neutral connection. The single-phasethree-wire system is the common arrangement used...
